Although the only limits on turbo tuning are your wallet and imagination, there are still a few steps to begin with that are wise to do for good performance increases on any turbo car.
1. REMAPPED ECU
If you do just one modification to your turbo car, make it a remap. Nothing – and we mean nothing – gives more gains for the cash on an otherwise standard turbo motor than a remap. This gives decent all round increases and takes as little as 30min to do.
2. FULL EXHAUST SYSTEM
Many turbo cars have very restrictive exhausts, so a full system can make a huge difference. We would recommend a turbo-back system though, as the downpipe is often the most restrictive part.
3. INDUCTION KIT
Although many would suggest heat soak from a cone filter is a bad thing, an induction kit is usually less restrictive than the standard airbox, improving breathing and transforming the sound of the engine too.
4. FRONT INTERCOOLER
Standard intercoolers are only designed to cope with standard boost, so even after a simple remap an uprated intercooler can provide good gains. It should also make the car more reliable due to cooler inlet temps – a win-win situation.
5. UPRATED DUMP-VALVE
With increased boost pressures from a remap, most standard dump valve springs and diaphragms often aren’t strong enough to cope, allowing the dump-valve to leak when on boost, denting performance. So get a better one.
